Same happened to me - snailed in the 80's then saw a Showtime sweeps & entered it/looked for more but nada - until I got outside my head & was voting for a member [diff site] & hit an IW for $100!
The sweeps are the sweeps - your chances really don't change, just your timing does
The sweepers credo
Sweeping is a hobby that is all about timing. Especially for those elusive instants! IF you enter at the exact right moment, you will win. If not? Sad to say you won't. But I assure you - it's nothing personal, and those who win a lot don't have any "secrets" - they are just consistent, persistent, and patient.
The sweepers credo? Enter and forget it. Always be happy for those that win - even when they win "your" prize

- and be positive you will win.
Reminding myself of the sweepers credo is how I keep my positive attitude, and my sanity.
I really believe that if you go into it thinking you can't win, well, you'll MAKE yourself right so often you'll start believing it!!! I truly do believe you have to have a positive attitude - don't get hung up on what others are doing - just focus on entering, then move on to something else - like posting so we can get to know you!
Hang in there - and enter, enter, enter - you'll be posting a win before you know it!!! And remember - every day brings new opportunities to win!
