Professional Guitar Backing

i im 22 yrs old and want to learn to play drums guitar and piano but i cannot afford a tutor

i will be going back to college in september and i will also be working. Is it a bad idea for me to try and learn to play all these instruments at the same time and i wanna be really good lke the professionals how much time do i need to practice per week is an hour a day good?

OKAY
i play all three instruments:) well guitar im just learning now on my own... u can teach urself the guitar and the drums u will need a tutor for the beginning i had one for about 5 lessons im playing for 6 months and every1 says i am very good for that length. i dont even have a drum kit:) to practice i just tap rythms well i put on my earphones put a song i wanna learn and i use fingers as drums ticks or use my real sticks and tap rythms.
piano i had a teacher too but that instrument does not really appeal to me muccha nymore. i have a keyboard i practice drums on it as well i change the voice of gthe notes and also i play the piano it (duh) and i have also got a guitar. i got the guitar about 1 week ago and i play songs i like which are easy from www.ultimate-guitar.com they have tabs for u to learn from once u can read them it will be really easy playing any song.
i suggest u choose one instrument for the time being my go would be guitar and drums first get a drum teacherfor about 2 weeks lets say 2 or 3 times a week and then u should know alot for a while u can try teach urself the rest and guitar as i said, teach urself there are also videos on youtube on how to play instrumetns especially many drum tutorials etc.
hopethat helps.
