Humans are motivated by 2 things.
Reward (desire)
Punishment (fear)
Either stick Or carrot. Either you seek pleasure or avoid pain.
Both are feelings — subjective. That means you get the benefit or you get the pain.
Ego drives you. Whether you like it or not, it is the truth.
No man can motivated forever Unless they derives satisfaction and happiness from the thing they do — not from the result of it.
2 Secret ingredient of achieving perpetual motivation
1. Autotelic
When the work you are doing itself is your reward.
2. Autonomy
Freedom.
When you set your challenges yourself. When you’re allowed to make mistakes and make them right in your way. Learning things in your way.
In short,
Just do it. Do it for the sake of it. Do it in the way you’re happy to do it.
But to win big,
The goal you set and remember why you need to achieve it badly is your source of motivation.
