Decide with your heart, and then do. Deide with your heart, then stay decided until the job is done.
Decide to do what you know is right for you. Then don't let anything stop you from getting it finished.
Feel the fears, and then move forward anyway. Each time anyone tells you why you can't, remind yourself again of why you must.
If Circumstances are less ideal, so be it. You can deal with the challenges as they come, and move steadily toward the achievement of what you have decided.
Decide with your heart, and you will naturally be committed to that decision. Whatever may come, you will know you have what it takes to get the job done.
From the depth of your being, from the truth in your heart, decide what you will do. Then delight in the process and in the fulfillment of getting it done.
