Unrealistic Changes

I have came a long way since the summer and have changed my appearance quite well by losing weight. Unfortunately, it's not enough and I not only want to change myself, but to better myself. At this time, I am feeling a very strong weight, giving in on me, and every second I feel like giving up, I'm moving  so slow and the pain is quite extreme for me to bear alone and in silence. I have came up with a list of things I must do in order for me to not only endure this time, but to overcome it. The list includes:

1. Strengthening my relationship with God by reading the Bible more frequently, praying, and fasting.
2. Rarely eat to show we don't need to be self indulgent, along with a number of things humans tend to overdo.
3. Work out harder and more frequent, sounds pretty silly to physically exert myself on less fuel, but I like to think it's possible.
4. Speak more clearly, boldly, and with being an exemplar in mind. I don't have to speak often, I just have to do it well and at any time with ease and smoothness.
5. Stop procrastinating firstly with school work, at least achieve a B in all classes, then with Youtube, and after The Dankt Shop.
6. Keep my priorities in check, always ask if what I'm doing is top of the list important and always trying to do something to progress myself.
7. Always do everything virtuously, with honor, loyalty, purity, integrity, gratitude, and especially loving in mind.
8. Work out of my shyness and don't overdo myself to impress others, know I'm always a secluded person.
