Sometimes we get so bogged down in the daily grind we forget why we are doing what we are doing in the first place. Everything becomes a drudgery and it feels like we are wading through mud and getting nowhere. More of the same day in day out. Getting nowhere. If that's how you're feeling then perhaps you've lost sight of the BIG picture - your goal/dream. There is an old saying "can't see the wood for the trees".
Meaning: If you can't see the wood for the trees, you can't see the whole situation clearly because you're looking too closely at small details, or because you're too closely involved. For example: If everyday you focus on the small things you do without associating it with the larger goal then you can get lost in the micro ecology of your life. (Ooh that sounded profound even for me).
So I recommend you look up occasionally, not only to check your bearings and ensure you're still on track , but to enjoy the view and contemplate the endless possibilities that are open to you.
Stop, look up and take a breather - even for one moment - it will revive you.
