You're not weird for loving to see others succeed, in fact if you do, then you're a blessing and a motivation. I strongly believe that helping and encouraging others is one way of attracting blessings. Strife, jealousy and every other callous feeling will only demote and damage. If we can be happy for others, happiness is bound to remain with us, like karma, And moreover, our lord says to love our neighbors as ourselves. You're a good example.
