Motivation and Advice

[Cicero]

I am starting P90X for the 4th time (I quit half way the other times) and I need some motivation.

How noticeable will my results be at the end?
Will the results be enough for me to play football for the first time? (American football for high school)
How noticeable will be the results within the first month? (1/3 of the workout program)
Is it weird that I save pictures of guys shirtless? Would that be motivational? Is it to you? (I believe I'm straight but curious)

My body info is:

16 year old guy
5 foot 8 inches
135 lb.

Jason, i'm about an inch taller than you, and i'm 220lbs.
the secret is to eat more, and lift heavier.
most routines don't really differ in gains, just in technique or tailoring to you.
for me my routine is something like

Monday - shoulder
Tuesday - Back
Wednesday - Chest
Thursday - Legs
Friday - Biceps and Triceps
Saturday and Sunday - rest day

Shoulders:
standing BB military press
Front DB raises
Arnold Press
Side lateral raise
Reverse flies

Back:
Wide Grip Pulldowns
Bent over BB rows
Deadlift
Single arm DB rows
Seated wide grip rows
Shrugs

Chest:
Flat bench DB press
Flat bench flies
Decline BB press
Incline BB press
Lower chest cable crossovers
Pullovers

Legs:
Barbell Box squats
stiff legged deadlift
db lunges
leg extentions
standing calf raises

Arms:
BB curls
Rope pushdowns
DB hammer curls
close grip bench
Seated DB curls
Dips

reps 8-12, 3/4 sets
for legs reps 10-12, heavy enough to go to failure.

i've been on this with only minor changes for about 2 years, and i've gained around 15-20kg of lean mass.

the key is to eat.
just eat and eat. every 2-3 hours, keep your metabolism ticking over.

anything else you need let me know

EDIT:
saw you wanted motivation aswell
