bird

Actually it's considered inferior to E4 D4 and C4, and you get a disadvantage most games. Good luck buddy.

Saying "f4 is the best opening" because you like it is like saying French Fries and Ranch Dressing is the healthiest food because you like the taste.

By the way - Ranch - YUCK!

1. f4 exposes a diagonal that the king is on and does not help to develop any pieces. There are many better options.

good lord....

Feel free to play 1.f4 if you wish, but first get familiar with the most common positions that arise from it.

Don't encourage him...

1. f4 e5 2. g4 and in this position, black resigned...EASY! This is the critical line, for the supremacy of 1.f4 xD

GRRRRRRRRRRR...

I've given up on 1.f4 and started to play 1.h4 instead. My results are a lot better.

This should be in off-topic now.

Reminds me of https://www.chess.com/video/player/double-bishop-sac-insanity

Let's take a look at the opening prinicples. 
1. control the center

2. develop pieces

3. castle

f4 controls the e5-square, so it helps taking control over the center.

f4 doesnt help to develop any piece, whereas moves such as e4, d4 or b3 help a bishop getting out.

an opening must provide a quick and safe castle. the light squared bishop cant get out relatively quick, and it breaks open the defending f2 pawn. You can castle queenside, but it takes longer and most of the time you dont want your king in the center.

thats 1 dicipline out of 3. There is also another floor with the bird's:
