I can suffer from fatigue after too much time moving from one thing to another. However, if I am being productive it is not a problem.
What you are doing sounds interesting and rewarding. I am also in the process of building a profile on Upwork. Remote's AI was matching me with mismatches; I think that site is still work in progress.
In IT and web design, there is always more to learn and the technology moves so quickly. I was doing a Cloud Infrastructure Technologies course and it's mind boggling! Working, learning and progressing is a great situation to be in though.
Right now, I am probably most effective at activism, analysis and politics. They go hand in hand and I feel within a certain drive and passion behind them.
I hope your business continues to be profitable and rewarding.
