Those 2 hours aren’t a complete waste, they’re also part of optimizing the hustle because those 2 hours led you to that 1 hour of effective work.
But from my little experience, to optimize the hustle, you have to read relevant literature and updated content consistently. You have to apply yourself in new fields, learn them, practice them, fail at it but still persist at them. You have to find a mentor, someone relatively young and smart that has optimized his own journey to success to help you out.
There are more factors to it. But the above counts a big deal. At the end of the day, your ability to learn rapidly, and fail faster will optimize your hustle eventually.
And always remember, the day after you give up is the day you succeed.
