I think a lot of times those pressures don’t come from ourselves and that’s why they’re painted as good or bad. Whether it’s parents, family, or a significant other it’s usually someone close enough to us that we care about their opinion and understand our choices can affect them, but we have to decide at what point we need to be in control of our own decisions and the life they create. If we decide not to take on the responsibility, that can be seen as selfish or childish, and against their wishes, so often taken as bad. Even if it brings us more happiness.
I think you have to look at motivation in that situation. Is the person looking out for you or trying to help you learn from their mistakes and regrets? If so, then that’s a great time to look at your direction and decide if you’re truly happy with where you’re headed. How sure are you? You don’t necessarily have to change, but look out 10 or 20 years and see if you’re still happy renting your house, or not having kids, or in your current job. If so, awesome, one less thing to worry about, tell them you’ve got it under control. If you’re not happy with that future, then it’s a great time to start looking at alternatives.
On the other hand if someone is trying to get you to take responsibility so they don’t have to, or for other reasons that have nothing to do with your well being, then I think that’s a good realization too. If your parents want you to have kids so they can have grandkids, that’s not really their decision to make. If your partner wants you to work towards the big promotion so you can improve your shared quality of life, that’s a little tougher, but ultimately you have to work the job. Is the total change worth it?
It’s a lot easier to take on and keep up with responsibility when it’s your own decision and those choices are some of the ones that really define what kind of life we have and the connections we maintain. I can’t remember regretting a decision that felt natural at the time, even if I gave up a lot for it, and if it didn’t work out like I wanted. So I try to make sure the responsibilities I take on at this point are my choice, and that makes maintaining them so much easier.
When you think about it that way, choices become easier. If you’re excited about a job, pet, house, or kid… do it. If you’re not excited, but it will make you happy, do it as long as it makes you happy (realize kids and pets don’t go away). Anything else better be a really short sacrifice for someone who deserves it.
