Takes time and practice to develop finger strength, muscle memory, rhythm strumming. Keep at it
And dont give up.. i always say, practice, persistence, perseverance and passion will eventually get you there
Happy Strummings. ..
Just remember everyone is different, their hand and finger size, strength, dexterity, and ukulele necks are wider or narrower
And slim or thicker.. choose wisely. if your action and string height is high, it will be harder to fret ..get a set up
Last is string tension..the higher tension strings gives you better clarity but is harder on your fingers, low tension strings is warmer .. good luck man
And improves comfort and playability. .
