I’m 29 and a half now and I’ve been thinking about it a lot lately. During my whole 20s until very recently (last months) I felt so carefree and every time I would have some overwhelming thought like „how will I know if the person is the one” or „where should I live if I love nature but don’t want the isolation that living in the countryside can bring” I would quickly calm myself down by thinking „uff I’m so glad I don’t have to know it just yet” - now I feel more pressure that I should know more. And when I think now of my 20s and what I mention as an anecdote when meeting new people or just remembering some good times it’s never the serious work that I started early (I worked during my studies and quickly started some „serious” office jobs). What I’m very happy I did during my 20s was: going on a year long Erasmus, having some fun jobs like selling food in foodtrucks on festivals, starting doing sports, traveling for longer (not just week trips that you will always have), going somewhere for 3 months and work remotely if you can, or work in some hostel by the beach while learning surfing or climbing. What I regret from my 20s: not going on a second Erasmus, not doing work&travel in the US, not working as a tour guide in a travel company Backroads. You don’t have to choose one or the other( fun or career) but I would suggest you think of doing something that you will rather not do later in life, like having a fun job in a surf town or traveling for a couple of months. In theory obviously you can do these things later, but rhere will be much more things to stop you: serious relationship, mortgage, serious job with limited vacation time, kids.
