Habit building (and breaking) is one of the hardest things we can do, but it's also one of the most important for our long-term success and happiness. What I find to be a good rule, however, is the 30-day trial period: If you can sustain an activity for the duration of an entire month, no matter how unpleasant or uncomfortable it is at first, it will develop into a habit. Here are five simple daily habits that have the power to change your life for the better.

1. Make a morning routine.

Something we all fail at is having a consistently good way to start our day. There is comfort in repeating the same set of rituals each morning. When we grow accustomed to sipping our morning coffee over the newspaper, we ease into waking up. Setting a routine in stone is a way to grow comfortable starting a great day wherever you are.

2. Do one thing at a time.

Multitasking, despite its alluring appearance, is really our downfall. Doing more than one thing at a time fools us into thinking we're being productive when, in reality, we're not really getting anything done at all. It's one of the hardest habits to break but once you do, you'll be surprised by how much easier it is to finish a to-do list.

3. Clean up.

Even though some think that a cluttered desk or office aids the creative process, external clutter ultimately leads to mental clutter. Opting for a minimal approach will allow fresh perspectives on life. Clean up your work area regularly and often. It'll change your life.

4. Stay hydrated.

Not drinking enough water leaves us with headaches, encourages us to overeat, and dries out our skin. Missing out on fluid consumption also just prevents us from feeling healthy and rejuvenated. After all, juice cleanses wouldn't be so popular if they had no merit.

5. Wake up early.

Make it a habit (just like your morning routine) to wake up early -- preferably no later than 6:00 a.m. each day. Try to get up at the same time, more or less, each day. Disrupting our sleep cycle by changing our wakeup time is actually not conducive to productivity. It'll be hard at first, but try to rise earlier consistently, so you can always live your fullest day. You won't regret it.
