Day 12: Plan B?

Is it important to have a plan B? Because recently I realised I don't have one. And today in my internship masterclass we were told it's very important to have a plan B. I honestly don't agree with this. Yes I agree that even the best laid out plans don't work out but as long as you have another one to fall on you wont give plan A 100% anyways. If you already have in mind a plan B, how will you ever get the motivation and thirst to go after your plan A and make it true. I don't have a plan B and neither do i want one. I have one plan and I'm doing everything in my power to make it happen. And I'm sure my hardwork will pay off because I truly believe in it. I'm so sure of my plan that I don't need another one. I'm determined to pursue it and I'm so certain of it that I never even thought of making a plan B. i think that plan B diverts you from your plan A and this might sound extremely arrogant or over-confident to some people but I believe in myself, my hard work, talent and confidence to achieve my one and only plan or as most people have it, their 'PLAN A'.
