Heb 13:5Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
You have one, give the others away to who ever the Lord puts on your heart to share with. Maybe you have the means to own 3 boards, but you may have a friend that cant afford one, so you could share with him or her.
Its not wrong to have possessions, but do not let them have you! I should know, I was living in great idolatry, greed, and covertness, for many years,until I repented of it all, gave much of it away to the poor, got out of financial debt, and now live within my means.
But remember if you spend your time indulging in these pastimes, more than you seek truth, and study the word to show yourself approved to God, then you are coveting up Idols!
So repent, clear your heart, seek truth with all your heart and soul, get hot for God and living a clean righteous life, with a heart made pure through faith and repentance.
Then you will be able to see clearly why seeking after material possessions is wrong, and can lead to idolatry! If your heart is pure, then your motives will be also.
