Embrace your constraints. We all experience some form of constraints at one time or another and are often disheartened when we do so. However, what if we reframed the constraint as an opportunity to grow and accomplish.
A time constraint might force you to become more productive by improving your ability to prioritize more effectively and removing some of the non-essential activities in your life.
A financial constraint could help motivate you to improve your skill set to earn more money. It could also push you in to being more creative about how you get what you want, or move you to ask the question do I really need this right now or ever.
Constraints to some extent force you to make a decision which is the only way that you can move forward and learn. Studies show that some of the most unfulfilled individuals are those that are unconstrained and have an abundance of time and money, because they do not know what to do with either.
Changing your perspective on how you see your constraints will help you learn to use them to your advantage.
