What is the entire meaning of this ayat?

Surah Bani-Israel(Al Isra17) 

Ayah: 26 	
"Arabic: 	وَآتِ ذَا الْقُرْبَى حَقَّهُ وَالْمِسْكِينَ وَابْنَ السَّبِيلِ وَلاَ تُبَذِّرْ تَبْذِيرًا
Pickthal: 	Give the kinsman his due, and the needy, and the wayfarer, and squander not (thy wealth) in wantonness.
Shakir: 	And give to the near of kin his due and (to) the needy and the wayfarer, and do not squander wastefully.
Yusuf Ali: 	And render to the kindred their due rights, as (also) to those in want, and to the wayfarer: But squander not (your wealth) in the mannerof a spendthrift."

I'd like to know that what is meant by "..and do not squander wastefully." Did it exactly mean not to waste money here and there/ meaninglessly or did it mean that we should be conscious about how much we are giving money in charity or in others help, so that we don't give more than our limit that should be given in..
