Here's a fact: nothing is permanent in showbiz!
Even young ones in the industry are aware of that.
Many of them actually have drawn up their Plan B as fallback in case their main source of income runs dry.
They've become entrepreneurs with thick business portfolios.
And, usually, their business ventures have been inspired by their hobbies or passions.
Ella Cruz, for example, loves to dance. Now the 21-year-old Viva Talent has opened a dance studio in Quezon City.
GMA-7 actor Rocco Nacino, with his fitness background, has put up his own franchise of Elorde's Boxing Gym.
Here are other celebrities in their 20s who are into multiple business ventures.
Alden Richards, 26
Alden has invested his money in a food business called Concha's Garden Cafe.
The first one is found in Tagaytay City, and the latest branch is located in Quezon City.
Alden is also preparing to open a gasoline business, which will be managed by his dad, Richard Faulkerson.
The Kapuso actor told PEP.ph (Philippine Entertainment Portal) in a previous interview that it was his father who inspired him to go into business.
He said, "Kasi that’s what my dad keeps on telling me, kasi we’re given so much blessing of things na puwede mong mapalago in the future.
"So it’s more of securing the future for family, for mga kamag-anak ko, kasi before you help others, you have to help people inside the family."
Maine Mendoza, 22

Kris Bernal, 28
In 2016, Kris opened her first burger stall called Meat Kris at the Communeaty Roces Food Hub in Quezon City.
Now, the Impostora star is setting up a new branch in Sampaloc, Manila.
In a previous interview with PEP.ph, Kris said burger and pizza were her comfort foods, and that gave her the idea to put up her own food business.
"Ako iyong gumagawa sa bahay bago ako umalis, lalo na kapag wala akong work.
"Or mommy ko, tinutulungan ako gumawa ng patties sa bahay, 'tapos dini-deliver dito.
"Talagang from raw siya galing, lahat ng patties namin delivered fresh every day, and handcrafted lahat, sinusukat namin.
"Isa-isa talaga naming ginagawa yung mga patties."

Kris shared a teaser for her new business venture in an Instagram post last November.
She wrote, "My 2018 PROJECT: #SEOULMeat Restaurant, Unlimited servings of Korean barbecue for less than P400. ????
"Learned so much about food business while handling my #MeatKRIS burger stalls, it’s time to create something bigger, dream bigger!"

"I want friends and family. And I have my own beach front! So everyone can surf, that's where I surf."
