Do not know how to do something? Chances are, you would turn to YouTube these days.
People worldwide have turned to the online video-sharing platform in droves to master tips that make their lives easier.
Even professionals - from chefs to leather crafters, music instructors to photographers - have picked up a trick or two.
Mr Yeo Chern Yu, 22, the chef and co-owner of Stateland Cafe in Bali Lane, learnt how to make the cafe's signature dish, its classic honey toast, from YouTube last September.
The dish, comprising bread baked with honey and salted butter that is served with berries and a scoop of honey yogurt gelato, costs $11.90 at his cafe.
Mr Yeo, who holds a diploma in culinary and catering management from Temasek Polytechnic, watched YouTube videos on cooking while serving national service.
"Whenever I was free, I'd be in the bunk watching videos," he says. "YouTube is fast, easily accessible and free. If you missed anything, you can re-watch the videos."
Thanks to these 24/7 tutorials, some have been able to hone certain skills without formal training.
Part-time guitar instructor Ian Kwan, 21, has been giving lessons at music school Drumstruck Studios at PoMo shopping mall in Selegie Road since March. Four 30-minute lessons with him costs $150, and he has six regular students.
Next month, he will perform at a concert at the Max Pavilion at the Singapore Expo, which features Indian film composer and singer Anirudh.
Three years ago, he took music as a higher level subject during his International Baccalaureate examinations and scored the highest grade of seven.
Yet, Mr Kwan has never gone for a guitar lesson in his life.
He picked up his guitar skills mainly by watching YouTube videos, which he has been doing since he was 13.
"Back then, I had a lot of time but little money. Naturally, I turned to YouTube," he explains.
From the videos, he learnt basic techniques such as how to play scales and chords. Then he progressed to more advanced techniques such as tapping and string-skipping.
He estimates that 70 per cent of his skills were gleaned from YouTube and the rest from other websites.
Now he can comfortably play more than 100 songs of different genres, from pop to rock, blues to funk.
He says: "I still watch the videos every day for an hour before I go to bed. They inspire me because I get to learn from musicians everywhere, such as Thai guitarist Jack Thammarat and American singer Allen Stone.
"Better still, I don't need to leave my house to attend 'school'."
At leather goods firm Forest Child, its three leather crafters credit 40 per cent of their skills to YouTube.
Ms Rozeryna Rothman, 29, Ms Addynna Azlinor, 28, and Ms Adlina Adil, 29, set up the business two years ago with no formal training apart from two mentors who taught them some basic leather crafting principles.
