Reddit mentions of 30KG DUMBBELL FREE WEIGHTS SET GYM BARBELLS

Won't disclose my exact age but it is similar to yours <21.


Snacks: If you get hungry, drink water first then go for something to eat. Depending on your height and weight, you will need a different amount of water. I use an app called 'Water your body'.

A good healthy snack I would recommend is granola or seeds. If you have a blender or a food mixer then you can try making yourself smoothies.

I used to drink 5 cups of coffee a day. Coffee fueled me, if I didn't have coffee I just shutdown. It was not good. Since completely giving it up (completely cold turkey), I have found I have better natural energy levels and just feel better in general. It's really great.




Getting fit: Gyms are expensive. If you don't want to shell out for one, order yourself some weights, such as the one here and start doing curls and other weight based exercises. You can also try some of the work outs on this website, there are lots of workouts for abs, biceps etc. Also check out /r/Fitness





Code: Get stuck? Use stackoverflow, your question has been asked a million times, trust me.
I'm not sure on your ability, but many have suggest codecedemy. I would recommend this too but also coursera.org and udemy.com they contain hundreds of free (or cheap) courses.
You can also try youtube, there are lots of channels dedicated to programming, such as this one here. He works on Game programming (which is a really good way of learning), he includes the resources and the videos are very well done.





General: If you just want to generally improve then try learning a new language. I am currently learning Spanish (using Duolingo) and Korean (using a variety of resources, such as memrise, koreanfromzero and koreanclass101), I've made new friends because I'm learning these languages using an app called 'Hello Talk'. It makes you a more interesting person.

You can also try picking up a hobby. Sounds generic but try playing the guitar or another musical instrument, this will also improve your hand-eye coordination. Kill two birds will one stone and start cycling lots.

Another huge thing, is get to sleep early. I speak as a bit of a hypocrite on this one but going to bed at around 10:30pm really helps my energy levels through the day and helps me to be sharper.




Skin care: You didn't mention this specifically but thought I'd throw it in anyway. I have found that drinking 2L of pure water each day really helps with my skin. I also highly recommend vitimin B5 (found in most B multi-vitimins. sometimes listed as Pantothenic acid) as well as Omega-3 (I use a tablet but you can use the liquid).
Another good tip is to change your pillow cases every couple of days, if not every day.

Obviously I do not know your skin type, but these are things that worked for me.




Getting things done: Again, didn't mention this but I often find this a problem.
I have recently starting using Trello to coordinate all of my todos. Keep a very detailed to do list or you will forget it. To not have to remember anything about what to do is satisfying because rather than worrying about what homework you forgot or whatever, you can simply look at your todo list and work through it. Here is a good read on this principle. (You can find the pdf online).
A principle I use is that if it takes 5 minutes or less, then just do it now. Tidy your room for 5 minutes, it may look like a horses stable but it really doesn't take long.



I hope this helps! Obligatory wall of text apology.
