Accomplishing anything worth accomplishing takes discipline. Let's take the gym for example.
Going to the gym regularly isn't easy.
First of all, you have to pay for the membership, the gas to get there, and all of your equipment, not to mention the supplements, etc.
You also have to actually go there and spend an hour of your time working hard, lifting weights, running, etc.
Worst of all? You won't see any progress after your first day. Or even after your first week. If you're new in the gym you may see strength gains after a few weeks, but you won't notice a visual difference for months.
And after you've been lifting for years, you'll have to work even harder for gains that are few and far between.
But if you have the discipline to go to the gym day after day, week after week, month after month, year after year, you will most definitely benefit and see massive results.
You'll be strong, in shape, healthy, more energized, more confident, live longer, etc. Those are all tremendous benefits, but they take work, and you won't receive them upfront.
You have to make a hard decision now to benefit later on. You have to be disciplined.
Discipline compounds. One proper decision leads to another. Likewise, one bad decision leads to another.
Think of it this way:
When you wake up early, you're starting your day with something hard instead of something easy. Now that you're already up, you might as well do something else hard, like exercise.
From there, you can start your homework, or get a hard start on work, or call another client, etc. Success compounds and you build momentum.
Conversely, if you start your day by sleeping in, you'll lazily get out of bed, and probably spend the next 30 minutes on your phone. Next you may skip exercise and eat an unhealthy snack, play video games, start work late, etc.
Which of those two scenarios is best for your long-term success? Imagine the version of yourself that wakes up early and gets sh*t done every single day 10 years from now, versus the version of you that wastes time, sleeps late, etc.
You must discipline yourself by waking up early so you can start your day properly and set yourself up for long-term success.
Waking up early will help you accomplish your goals.
