1) Those who contribute
2) Those who take.
I think we all go through times in life that are difficult and/or painful and we sit back and re-charge our batteries and we can’t (and maybe even shouldn’t) contribute for a time; though those times should be far-and-few-between though. In other words, those times should be “the exception not the rule”.
Challenge: Go through life making it better by giving, investing, sharing, loving … CONTRIBUTE!
Jesus said "I came to serve ... and to give my life..."
