I would say no, not these days. If you look at people who claim to have had their accounts "hacked" it wasn't really hacking as such, more like stupidity on their part (Sara Palin anyone?)
bludgeon has mentioned one of the most common exploits to "compromise" an e-mail account. Always lie when filling in the password recovery data
Others are:
1. Lack of physical security............never store login credentials where your kid brother can access your machine.
2. Always logout properly, and clear the internet cache if you are using a machine to which others have access. You don't want to leave an open session for someone else do you?
3. Watch out for insecure public hotspots, your traffic might be sniffed.
I would only rate #3 as close to hacking, and it is probably the least likely.
