I went to college with the intent of learning to design bridges. Initially I had a little twinkle in my eye to one day design a landmark bridge like San Francisco's Golden Gate Bridge. But eventually I came to realize after some genuine reflection landmark bridges were one in 10,000 or more.
What were the odds of me one day managing a project like that? Not good enough. Far too much of that pursuit was too far beyond my control to dedicate a career towards. I didn't want government regulations, budgets, corporate bureaucracy, or time and place to control my dream outcome.
So I moved on.
What was key to me moving on was I knew what I wanted and I knew I couldn't have it. Too many people fall victim to staying in a situation they would otherwise leave IF they knew what they wanted. I just moved on to something else (water treatment design), I didn't even have a new goal in mind.
It's okay to give up on something you're interested in. It's not okay to give up pursuing your interests. If you're spinning your wheels yet again on this fine Monday morning, maybe it's time to move on to something else you're interested in.
Stop waiting to live.
