A Ph.D. is a big commitment, and there is no doubt that it is a big investment in your future career. Figuring out when to make this investment can be tricky, but there are a few factors to consider to find the right time for you.

For most people, their 20s are the perfect time to do a Ph.D. That is when your career is just beginning, you can take advantage of the opportunities that being a student provides, and you still have lots of energy and enthusiasm for the subject after several years of hard work. The problem, though, with youth is that they may not be adequately aware of the commitment a Ph.D. requires. One can argue that they are not mature enough to understand that they will need to work long hours to do well.

For other people, there are many benefits to starting a Ph.D. as late as in their 50s or 60s. You might have already achieved financial stability or professional goals, and carrying on with a Ph.D. may be something you want to do for yourself. On the other hand, it can be harder to do a Ph.D. as an older student because of a lack of time and energy.

Overall, the benefits and drawbacks of doing a Ph.D. at different ages depend on individual circumstances and goals. But your life stage will have a significant impact on your Ph.D experience and your career prospects. I think, overall, the right time to do a Ph.D. is when you have a stable life. If you are a single person, it is also important to make sure that you have enough time to devote to your research and still have the ability to have a social life.
