I'm planning out my new venture

So it's been a couple of days since my state of depression and stress. It's back to the book's and time to focus on what's ahead. One of my biggest difficulties at this time is managing my time to apply for internships, learn about the industries and maintain my studies in school. In one big category, you can say this is simply time management, but on a chopping board, you can see managing issues in each sector. I'm even entering an entrepreneurial contest in PA with a buddy of mine who spoke briefly about it. I just came up with this idea that I thought would be great! It's currently in the phase of creating a business plan. My main problems at this point is to manage my time and keep up with my studies like I mentioned earlier. Obviously, I have to prioritize school first, but I feel like I also have to put so much time into this business plan to make it work and on top of that, my birthday is coming up on March 7, and I have some credit card debt because I just had to charge the tuition on my card, and I even have to worry about the work I do at the job. Honestly, I want to quit my job at this point because I feel like it will be beneficial for my analytical skills to prosper, but I still need the pocket change for me to eat and stay in the city as much as I do. Waking up at 6:30 and staying out until 10:00 on weekdays basically means I have to eat out. There's no other choice. That's another problem, budgeting. I'm gonna have to focus, plan and focus!
