Try new things
Something that many 30 and 40-year-olds wish they did in their 20s had more fun. Life is about to get busier so this is your perfect opportunity.
Loosen up and allow yourself to go for holidays and trips with your family and friends, try new hairstyles, take up new challenges and eat life with a big spoon while you still have time.
However, don't use this as an excuse to be careless though, you will have my regrets.
Prioritise your healthHealth should be one of our main priorities in each stage of our lives. The habits you have in your 20s will affect you in your 30s and the habits you have in your 30s will affect you in your 40s, and so on. All this is to say, you should enjoy your junk food but in moderation.
Also, this should apply to your mental health as well. Seek therapy and counselling so that those struggles don't follow you into your 30s.
Find your career pathYou have a bit of time to find out what your career plans are. If you've been undecided for a long time, you can seek some guidance on which path is best for you.
This is important because you should start being more financially stable as you move into your 30s. You need to have a solid plan so that you don't end up struggling financially in future.
