It’s a challenging part for me when it comes to motivation. I forgot to pull myself sometimes and I drag myself deep down when I shouldn’t, I know it's wrong. What I do now is I really try to look for motivating quotes/message to remind myself not to give up. Staying on track takes a lot of self discipline, focus and inspiration.
Inspiration and positivity is possible however it was so hard to be positive when the people around you is pulling you down, saying negative things, like you can’t make it. But instead of thinking about all these negative ions around me I would tell myself that this would be my inspiration to do more, to be better, and to reach my ultimate goal. They will be shocked in the end that I did make it. This would be a sweet revenge to those people, right?
Here's a perfect guide to stay motivated ^_^
