If you tell me your dream is to be rich, I'll tell you to wake up. Stop framing your ambitions as dreams those happen when you sleep! Make it a goal. A goal is achievable in the mind vs the dream where it is bound their in. When it's a goal start marking down your next steps to take to get there and when your going to do it by. Don't forget the when.
Remember to establish the "why" by genuinely asking yourself why you want to achieve what it is you want. Go atleast three conseutive why questions digging deeper. This will supply the will power with enough gas to get you where you want to be.
Now for the last part add some accountability in the mix by telling your close friends and family that will help remind you to stay on track and hold you accountable to your promises to yourself.
