Portfolio 10+ years

Hi guys, Would like to know your opinion about my portfolio for long-term investing. Want to keep it simple so, but with little diversity: - MSCI world - 60 % - MSCI IT - 15 % - EU banks - 15 % - gold - 10 % Shoudl I get rid of MSCI IT and just go all world? Monthly income is more than 2,5k eur, want to invest 1,5k to portfolio and around 200 - 300 to individual stocks that I can lose Thank you
