You generally have one of these in limited supply. While we are students, we have money in short supply but an abundance of time. This reverses once we start working – suddenly time becomes a bigger problem than money.
Constraints never go away. We just need to stop viewing them as constraints and start thinking of them as forces that help us prioritize better. Yes, we’d generally like more time/money travel, hang out, and have fun but these constraints make sure we focus on getting what we need rather than getting what we want.
We do hear of folks who use lack of time as an excuse to not live happy lives. That’s bullshit in my opinion. Giving someone who moans about a lack of time more time will never solve the problem. As the quote goes, if you want something done, give it to a busy person.
Constraints are good. They help us live better lives. We just have to use them well.
