That's aging.

When you're young you spend a lot of your time proving that you can achieve what you believe you can achieve - both for yourself and as social proof to everyone else.

Once you've done that, and are comfortable with who you are and no longer feel you need to prove your worth, you need other motivations.

At that point 'growth' may come in different forms.

Go on a holiday, give yourself time to rediscover some interests and passions.

Or just be content that you have achieved what you spent a lot of your time trying to achieve.

Angel invest into small companies using your knowledge to nudge things politely. If growing gets old, create I guess..

> How do you keep yourself excited and focused on growth?

Do something that connects you with the greater world. For me? Hiking and traveling in a State with a lifetime of natural wonders to explore.

Try nature. See how amenable it is to you.

(I also play video games... too much)
