First of all, you need to define your goals, you need to clearly understand what you want to achieve, write down your thoughts and desires, this will help you better focus on your goals. Do not immediately try to pluck a star from the sky, break down your goals into smaller ones, several small tasks are easier to complete than one large one, you will better see the progress of more tasks and understand that you are moving in the right direction. Set deadlines for each task, adhere to deadlines, and discipline will help you achieve better results. It will not always be possible to do everything the first time, if you failed the first time, try again, given the mistakes you made earlier, it will help you get better and develop. You need to constantly develop and learn new skills, read books, find information on the Internet. Surround yourself with people who support your goals and are ready to help you in your endeavors, they will be a support, motivation for you and will help you overcome difficulties and achieve success.
In no case do not give up and always believe in yourself, then everything will definitely work out!! Have a nice day!
