Welcome.
Advice - write professionally to be taken seriously. SF is a cut above, laziness (mental or physical) can get you thrown out of the pipeline. You might just see some of the people from this board when you hit SFAS and, if you are selected, the Q course... they will remember little things - just sayin'...
Don't try to over G2 the pipeline - focus on the basics: strength - mental and physical; endurance - mental, physical and spiritual; field skills; flexibility in action; and an open mind... In SFAS - you will never know what's coming next, but it will require all of the above at all times.
