Roots of Pressures

I've been asking myself over and over again... "What really is my priority in life? Should I keep wasting my time on my studies and not enjoying the fellowship times with Brothers and Sisters or even enjoying life??"... What triggered my mind to think that way is really from my progress in seeking for Master's Degree and plus the fact that I've received a C+ this semester which means that I'd have to pay out of my pocket($3000+). As materials are getting tougher and pressuring, I often ask myself.. "What if life ends next month?? then will all of these hard works go in vain??" I am going for something that I don't really care about.. something that I really do not 'need'.. something that is only nice to have but yet it takes over all of my time, it gives me tons of pressures, and puts me in a depression mode. Although to a certain extent, this is really true... but what keeps me going are these reasons:
1) If I give up on this degree then I "might" regret in the future, but if I keep going I will never regret about having the degree and the hard work.(I will probably be proud of it. **Note-not in a conceited way)
2) Company is paying most of it, at least 80% of it.(that's if I do real well from now on)
3) God had definitely opened up all the doors for me in this path.
4) Even if world ends or if I die early, God still wants me to try my best in achieving something in life. God doesn't look at the results as I do but He looks at the process and efforts I've given.
5) I think this could be a great testimony and by leaning on Him while I finish this degree it pleases Him which means I am walking in His Will.

Overall, I think all of my pressures come from the mindset of "Needing to pay for it if I do not get a 'B' for the class"... that is correct that if I get a B then the company would pay for it for me, but if I just simply change my mindset into thinking that I am willing to pay regardless then the pressure would be gone.

Is money really an issue if I am forced to pay for the whole degree? No, not really, I can afford it but I just don't want to since I am saving up money, and looking to save up $120k in 4 yrs for down payment on a $600k house that I might get if God allows. But I should not limit myself/God with that thought, I will get whatever house God allows me to get at the time with whatever $$ He allows me to save in this 4-5yrs. God knows me the best... He knows exactly if I needed that house, He'll let me know if I will be single or married, and He'll even let me know if I will have kids. Who needs a big house when they're single or if they do not have kids??

My Lord is my Shepherd, I shall not want. Amen..
