Motivation is not really needed. It can be a direction. Like setting an intention. Effort comes first.
Is motivation like wanting to be on the next floor but instead of taking a staircase that is already there?Instead you are building an elevator. And maybe you dont know how to build the elevator so you need to learn that first. Because the staircase introduces too much friction. And maybe the next floor is too close anyway. You are not ready. Easy to get off track.
What is your desire? Why do you want it? What is your inspiration? Your brain will avoid effort. It craves for rewards.
And there is an interesting twist, once doing the action, motivation often follows.
