Do what you want.
やりたいことをやろう。
We often become passionate about something, but our passion usually doesn’t last forever.
It happens to anyone. You don’t have to make an excuse. Do whatever you want at any given time. Do everything you want. Do as many things as you can.
When you think you’ve found something important and your passion about it will last—verify it. And if your passion is true, congratulations! You hit a jackpot.
Don’t expect that you will hit a jackpot on your first attempt. It never happens to most of us. The person who hit a jackpot is someone who kept trying until he hit a jackpot.
