Find an achievable goal that you are able to complete within a manageable time frame.
The key to achieving your objective is to set your mind and focus 110% on your goal.
Just Do It. Don't let pleasure get in the way. Set yourself a time and get to work.
Build your strength, loss signs of weaknesses. Strength will give confidence in people and will earn you more respect.
Unless you are passionate, you will never succeed. Learn to love, and believe in the future of what you are doing.
Making the right choice can only come from experience. Go out, meet people and explore the universe you live in.
