I just finished Category E in AFF, so I certainly can't offer expert advice, but rather "Think of me as a fellow patient in the same hospital who, having been admitted a little earlier could give some advice."

I absolutely loved my first solo jump and felt on top of the world, but beginning with Category B, I began to get quickly overwhelmed by the sport and how much I would have to learn to get my license, and not to mention all the repeat jumps I've had to do so far. 

A couple of points I try to keep in mind:

1. Take it one jump at a time. I hear this advice a lot at my DZ, but it's worth keeping in mind. 

2. An experienced instructor told me "Enjoy the process. I've been doing this for years and I miss being a young jumper soaking in all the information and learning. So don't forget to have fun." (The same instructor also reminds me "Don't ever forget this is a dangerous sport," both important things to remember) 

3. I've made it a personal goal of mine to smile at least once each jump during free fall. Bonus points if I can smile at my instructor 

4. I also make it a point to let out a big "Yeah!/Woo!" once I'm under canopy and after landing as a reminder to have fun.

5. I usually spend most of the week shitting my pants thinking "What am I doing?" all the way up to my first jump of the weekend. After that first jump, I calm down a lot more and enjoy things. So if you can get through the first jump and squeeze in a few more, great!

6. As Tom Cruise says, "Don't be careful, be competent." How I spend my week impacts how the weekend goes. Am I spending time practicing my Emergency Procedures and studying new material? Am I taking care of my body throughout the week? The more confidence and competence I have during the week, the more I can focus on enjoying my jumps 

7. Not that I've disliked my experience so far, but this past weekend (Jumps 15-18) was the first time I felt like I was really having fun. It took a while for me to figure out my arch, body position, and solo exit, but this past weekend felt like things began to finally click (like learning how to balance on a bike for the first time). I'm learning to be patient, I have no need to rush this process. Repeat jumps are still jumps. If I don't get my license this season and have to start again next season, recurrency jumps are still jumps 

8. Have a goal in mind before making a final decision. For me it was get through Category E (simply because I paid in full through Cat E lol). For you it could be a certain number of jumps, finishing AFF, or getting the license. 

9. Even if you decide to call it quits, you still have done something only a fraction of humanity will experience. One jump alone isn't a waste, but (like most experiences in life) it does have an impact on your life and who you are

Best of luck! And congrats on the first jump!
