Virtually all the projections that I've read about investment returns in the next few years (and longer) strongly suggest that overall returns will be considerably less than historical averages. Thus, it is even more critical than ever to ensure that you are not paying too much for management fees and investment advice. Are you sure you understand how much you are being charged for investment advice in terms of adviser fees, commissions, and management fees? If your adviser is charging "only" 1% of assets under management, you had better educate yourself about how that eats into your returns.
