The most successful people in the world are the ones who are in a constant process of evolution. Not everyone makes the choice to grow, but that's not always because they're comfortable standing still. Sometimes people just don't know where to start their journey to the future. Here are four simple ideas that anyone can use to begin for self improvement .

1. Take a Break:

It used to be that graduating from high school led to the immediate start of college, a career or a family for the graduate. That's no longer true, and it's not necessarily a bad thing. According to research from Bestcolleges.com, students who take a gap year are more likely to graduate in four years or less than those who don't. The reason for this is simple: self-reflection. Students who go straight from high school to college are more likely to have set in their minds what they want to study, which results in better focus when they do start their studies.

It gets better. The Gap Year Association states that 93% of students stated that their gap year helped them to learn "soft skills" like communication and group coordination. The gap year phenomenon isn't limited to students either. If you're between jobs, now might be a good time to branch out into exploring some side interests that might turn out to be real passions.  

2. Feed Yourself Mindfully

Being conscious about eating can even help boost your work productivity. Managers have their eyes on three nutrients in particular: magnesium, phenylalanine and choline. All of them have a positive impact on brain function, with magnesium (found in dark chocolate and leafy greens) being shown by some studies to cut anxiety. If you want to change your life, start with what you put in your body.

3. Learn Meditation

Meditation is another good idea that's finally getting respect from science. A few years ago, scientists at Harvard Medical School discovered something amazing: after only eight weeks of mindfulness meditation, the amygdala (the part of our brains that governs fear response) became less active. In fact, as little as ten minutes of meditation have been shown to quiet nerves and give added focus. The benefits don't end there; people with physical conditions like multiple sclerosis can see a reduction in pain after meditating. 

4. Do Good for the World

Study after study has shown that giving back to others is objectively good for the person who does the giving. One of the greatest benefits is an increase in personal self-esteem. The reasons for this go much deeper than good vibes. Helping others in a more active way than simply giving from afar causes the same positive emotional reaction in philanthropists, even more so when they know the effects of their good deeds. That's right: The human mind is actually hardwired to reward someone for the good they do. It's not hard to see why. Everybody is connected to the rest of humanity in some measure, and when someone knows they're bettering that world in a tangible way, they realize that their own life has a purpose.

In the end, self-improvement isn't something you get from a list or a book. It's something you do for yourself, by taking a good look at what drives you as a person and then setting out on the right path for you.
