Be happy for other peoples accomplishments.
Be genuinely happy.
Doing so is not only good for them, not only is it good for your relationship to them, not only is it good for you; but it also invites abundance into your heart and into your life.
Now you might be thinking "Why the hell should I care about abundance?"
If you adopt an abundance mindset then you will invite prosperity into your life. You will attract more of what you want.
Your mind will not be closed off. You mind will actively seek out more for you.
More love, more money, more opportunities, more of whatever you are seeking.
Open up your mind, and that starts with you accepting the accomplishments of others, and being 100% authentically happy for them. Knowing that you will get yours when the time is right.
