Mostly not physical. Physical labor is the simplest and most affordable. To cope with your laziness, with instincts - this requires tremendous concentration on the goal and co-orientation of small steps!
It is fashionable to talk about motivation now, but what is “motivation”? It is a combination of internal and external driving force. Where to get it or how to develop it ?! Good question. I will say right away that the revolution does not work. Only smooth gradual successive changes and innovations. You will not wake up as a different person! But gradually you can create this person. Live with the motto: "no pity, no guile, no tomorrow." As you write this in your head, remember that new ideas are always weaker than old habits, so remind yourself again and again every day of responsibility - this is a position when you accept that only you are the cause of all the consequences in your life. When you realize this with every cell of your body, you will begin to feel confident as never before, because your life will be in your hands!
