How do I motivate myself to have motivation?

I've been told that I have little motivation and drive and that I give up too easily. However I'm sick of this. I'm still working at my same shitty job, I weight 220lbs when 160 is healthier (I'm 5'10) I haven't worked out in a while and I barely have the drive to ho to college even though deep down I want to get a higher education. I'm single because I give myself reasons not to go for a girl. I procrastinate everything. It's like my mind sees no point of even trying. I'm sick of it all an.d I wanna get thin/masculine and go to college, meet and date a beautiful girl, have an excellent job, and continue to strive. Please help me...
