It's impossible, the average person lives for 2,524,608,000 seconds, you do not have enough time to reach infinity. If you somehow managed to live forever, then after unveiling the mystery of immortality you somehow managed to flip heads successfully over and over, you would have to repeat this forever, because infinity is forever.
There is a 50% chance you will land on heads. There is is a 50% chance you will land on tails. There is 50% chance in every flip you make.
