time management is very important, you will turn 25, 30, 35, 40, 45 etc. time is coming for you, the best thing you can do is to develop a rigid and autistic daily routine that you can incrementally improve your entire life.
wake up every day same time, eat the same food, do the same exercise routine, wear consistent and comfortable clothes, keep a neat and orderly space around you, clean on a schedule, always be doing something physical a lot of your good ideas will not be coming from sitting down in front of a computer but from walking, gardening, riding a bicycle, talking to someone, reading a book, listening to music.
you will blink and half your life will be over and you will regret not learning important foundational things while your brain was still agile enough to capture the new information, so speak to someone older than you doing the same type of work and ask probing questions about what they are doing to see what gaps they have developed that you can fill in for yourself.
a classical problem that most scientists face is that they have little to no work inside a physical space, it's all head games and they become very self delusional about what they are doing with silly mathematical modelling. ideally you have a roadmap towards a product or device or material or invention which changes humanity, and you are walking towards it every day.
if you stay flexible enough to adjust your expectations but keep the rigidity of structure around yourself to maintain perfect health and brain activity you can go much further than more talented or gifted people who will naturally get fat old and stupid.
