I agree, we need some context. However, at my age (!) trying to look good does actually limit my life! I have to go to bed early! I have to put lots of goo on my face! (Look up 'goo' in the dictionary... I hope it's there!). I have to watch what I eat (diet). These things put limitations on what I can do. So from a very personal point of view I can answer this question. However, context would clarify if the speaker or writer of those words means the same thing.

I'm guessing it means that this person doesn't get to do everything they want to do in life because they are spending so much time trying to look great all the time. For example, putting on make up every day can take up a lot of time. Also, it's hard to look good while scuba diving, skydiving or hiking through the jungle.

I agree with Mike.

some context would help
