Let X, X (1), X (2),... be a sequence of independent and identically distributed random variables in the domain of attraction of a normal distribution. A universal result in almost sure limit theorem for the self-normalized partial sums S-n/V-n is established, where S-n = Sigma(n)(i=1) X-i,V-n(2) = Sigma(n)(i=1) X-i(2).
