Action.
A lot of people believe (including myself at one point) that motivation is supposed to come to you.
Tons of people as themselves each day “Why am I so unmotivated?”
The reality is motivation comes from action.
In most cases, you don’t start to feel any motivation until you’ve already got the ball rolling.
Recently, I started going to Judo classes in a town close by. I wasn’t motivated to learn Judo beforehand. It was only once I started training and learning a completely new skill that I was motivated to pursue improvement.
Now, I’m extremely motivated to learn as much as I can in Judo.
To boil it down, my advice for finding motivation would be:
Stop thinking and take action.
