Calculating the tunnel current between the electrodes via Bardeen's transfer Hamiltonian formalism, we can analyze the contribution of single electron states to the total tunnel current. Approaching in this manner an edge or a corner of the sample will help to understand the scanning over topographic features on real sample surfaces. This enables one to simulate a movement of the tip within any distance from the sample surface. The electrodes can change their mutual positions. The sample electrode is infinitely extended. The tip electrode extends infinitely along the vertical tip axis and has a small rectangular cross section facing the sample surface. Both tip and sample electrodes are approximated by square-well potentials filled up with non-interacting electrons up to their corresponding Fermi energies. Life is to be lived as long as you do so with a smart head on your shoulders, you wonвЂ™t go too wrong.Electron tunneling is considered within a model simulating the geometry of topographic imaging by a scanning tunneling microscope. To take steps that feel right without worrying too much about the grand scheme of things. In 2020, I dare you to experiment with life. YouвЂ™ll learn about yourself, others, and this wonderfully weird world we live in by simply taking steps forward. You may fall down along the road, but itвЂ™s all a learning curve. Trust yourself to do what needs to be done in any situation.

How else are you supposed to find what works in life if you never take any chances or any steps? Last ThoughtsДЄs long as you have a support system, a vision for what you want, and the brave and creative heart to go after what feels right, you will be okay.

No one else lives your life but you, donвЂ™t take advice or criticism too seriously.

You are not a tree: if youвЂ™re unhappy, move!.

Nothing is permanent everything is temporary.

You can always make a different choice.Some mistakes can stay with you for a long time and feel painful, but I believe we can sort of fix the past by changing our perspective of it or literally rectifying the mistake. Mistakes, missteps, failures are all so scary but usually, when they happen, theyвЂ™re not as bad as we thought they would be. Even if itвЂ™s a mistakeвЂ¦ДЄnd even if what you do is a вЂњ mistake,вЂќ you can always fix it. The more you think about something, the more likely you are to think yourself out of doing it. It is not possible to think yourself into a place of happiness and perfection.ДonвЂ™t think about every little detail. I know, IвЂ™ve been there many times before! The thing is, we can think something over until weвЂ™re blue in the face, but that doesnвЂ™t mean we are, necessarily, any more likely to find a perfect solution to our situation. Overthinking every decision is a fast-track ticket to overwhelm and stress. Let go, take the step, find your footing as you goвЂ¦ DonвЂ™t overthink it But not everything needs to be weighed up, planned, predicted, and controlled that much. Yes, we should think things through we should take calculated risks. To place too much weight on every decision we make. We all have a tendency to think too much sometimes. If something feels like the natural and next right step, then take it. Similarly, donвЂ™t try to control and plan ahead for what may happen. вЂњYou donвЂ™t have to see the whole staircase, just take the first step.вЂќ - Martin Luther King Jr. Just take the step which feels right for you. You neednвЂ™t think about the steps after that, or what this step may lead to. The next right step mostly means thinking about, and focusing on, simply the step right in front of you. Whatever youвЂ™re thinking, whatever is bothering you, donвЂ™t overcomplicate it: just take the next right stepвЂ¦ DonвЂ™t look too far ahead If you are someone whoвЂ™s a bit worried about the new year because youвЂ™re unsure of what to do next, then my advice to you would be to bear this in mind. Inspired by Frozen 2: when in doubt, when youвЂ™re afraid, just take the next right stepвЂ¦
