If you keep looking forward you're going to waste all of your 'nows,' the only time you ever really get! Sure it's nice to look forward to things, feel the pleasant anticipation. But what happens when you get there? Are you really satisfied? And for how long?
You need to give your full attention to the present moment. That's how life comes at you; a series of now moments.
Note these words which I read in a telegram to a couple getting married, many years ago. "Today is the tommorow you worried about yesterday." So don't worry about tomorrow. Look to today. It's the only day you have - and everybody has. The rest is either a dream or a memory.
