Stay determined
Always stay determined towards your goal, no matter how hard or lengthy it was.
Have discipline
Having discipline means the ability to do things even if you don't feel like so, merely sticking to the plan. Just show up, and the rest will come after.
Do not procrastinate
Don't ever put off today's work for tomorrow. Don't let things accumulate and try to do them when there's enough time.
Always keep the end goals within your vision
Sometimes, you may lose focus and get distracted off of your main goal, that's why it's important to visualize it and keep it somewhere you come across a lot. You can do this by writing the goal and the steps that are required to reach it, attach some pictures, and place it around your desk or place of study.
