I strongly suggest choosing the right market to serve. Focus on being the best, or one of the best in your niche.
The book “Blue Ocean Strategy” is a wonderful read to choose / create your own niche and be the best at it.
The key is TRULY understanding what your customers need, and what are their problems.
What do they really care about? Focus on that.
I included a summary of the Blue Ocean Strategy, as well as the top 17 books I wish I had read from the start when I started my first business. You can find them here (these books are invaluable. The Blue Ocean Strategy is at the bottom of the article):

Also, if you ever need inspiration the “Founders” podcast helps me stay motivated during my morning walks and start the day focused:

I hope it helps. Keep going!
For me it’s finding a balance that allows me to work hard, without needing constant “boosts” of snacks or caffeine. Also, getting enough sleep, which if not done right, leads to eating more than it is necessary.
