I am in the same boat. It's actually really interesting, after some careful though, I've realized that I've cultivated a habit where I come home from work and watch TV while eating some dinner. Afterwards, I always plan on doing work.

The problem is, that habit of watching TV with dinner causes me to sit down and get sucked into my TV habit. For example, last night I decided to do that and ended up watching 3 episodes of random shows and then going to bed, instead of doing what I wanted to do.

When I eat dinner and listen to a podcast, I still have a bit of an urge to watch TV but I find it much easier to sit down and get to work afterwards.

Maybe you have this type of habit in your own life? Try thinking about what you do every day when you come home from work, and identify your 'triggers'. If it's like mine and you are watching TV while eating dinner, listen to/watch a podcast or TED talk instead. If you end up spending a ton of time on YouTube or Facebook, set up something like SelfControl (or the PC equivalent Cold Turkey) to make sure that you can't use those things during times that you have blocked off for work.

For mac users, here's a list of stuff that you can use (note that I'm not vouching for any app in particular, but they all seem useful to someone): http://mac.appstorm.net/roundups/productivity-roundups/15-ma...
