It is time to invest in your education and development. There may be a course you have been meaning to take or a conference you have wanted to attend. Do not wait any longer, as you are your most precious asset, and you should invest in yourself fully.
You and your growth are all you can truly control after all. Even your professional projects are vulnerable to an element of uncertainty. Why not, then, invest in your education and growth? Sometimes the cost is a hurdle, but finding and making the time in a busy schedule is usually the hardest obstacle.
