To stay motivated it is important to stay organized. This pertains not only to keeping up with household things but also your social group. You are more influenced by your peers and those around you than you can imagine. This doesn't mean you disown your friends but instead to consider the amount of time you spend with the ones who lack direction or desire to better themselves. Spend good amounts of time with your mentors and people who have found a path that is appealing to you or how you would like to be seen in the future. Doing so will also give you the knowledge to encourage those friends that are having trouble finding their way and you can be a peer to peer role model for them. Life is short and is supposed to be enjoyed and for myself that is eliminating stress in all aspects that I can.
The other part to mention about organization is simply putting order in place in your life. In the last section I mentioned stress elimination and cleanliness is a huge one. Keeping clean will not only impress those around you but will also give you the confidence you need to continue to succeed. Wishing you all the best.
