Recently I read something like the following in a book:

Don't think that any the stuff you learned or did was useless.

That carries a strong message. Whatever you are doing today and whatever you might think about it, don't underestimate the role it could play in your future business.

Maybe just because of that experience you have an unfair advantage compared to a competitor. Or you just get a job because of that single experience that you had in your past.

Back to the future...
