Motivation is key, so is a positive environment. If you are surrounded with people that have the same goal, you will be more motivated to achieve your goal.
Search for people with the same interest so you can talk with them about it. Talk with them about it and try to gain knowledge. Also, share your own knowledge and experiences so others will be more interested in you.
Lastly, you shouldn't be jealous at others. Everyone has their own positives and negatives. The reason why people are jealous is that they forget about their own positives. Instead of bein jealous, you should give them compliments about their succes. And don't forget to be proud of yourself!
